Did you catch this part? "I don't just mean Erie PA."Only the grossly uninformed would fall for this comparison. The Erie steelhead fishery is entirely man-made and would cease to exist once stocking of smolts stopped. It is as much an artificial fishery as the trout pond at at Sea World.
We could catch all the spawing fish and stomp every redd in Erie County and it would not impact the steelhead fishery one bit. Same goes for NY and OH and many of the Great Lakes migratory salmonid fisheries.
Does angling affect some trout fishery, somewhere? Sure, of course, but using Erie steelhead as an example of hypocrisy misses the mark by quite a bit.
Yes, Erie PA is probably 99% stocked. That's why I said I don't mean Erie PA. I was really talking about Michigan, heck even Ontario (CN) etc. Fishing for fall-run salmonids (not just Erie) is normal. Natural reproduction or not.
However, recent work using otolith microchemistry indicated that 41% of Lake Michigan steelhead caught by recreational anglers were the result of natural reproduction (Breaker, 2020), with wild fish assigning to Wisconsin tributaries contributing very little (<10%) to the lakewide fishery.
These management changes to the fishery have been accompanied by variation in natural reproduction rates of Chinook salmon, which can range from 45 to 70% annually based on adult salmon growth and health, river levels and temperature, and availability of prey for youngsalmon.
- Pere Marquette River: 100%
- Grand and St. Joseph rivers: 10–20%
- Wisconsin tributaries: <10%
(that one is Lake Ontario)In fact, he said that it’s well documented that about half of the new salmon entered into the lake are produced naturally, meaning adult salmon enter tributaries where they spawn, fertilize, and produce eggs which become fry which become little salmon.
